This class implements a simple wrapper strategy object that defines a unified interface to seeding methods, that are used to initialise NMF models before fitting them with any NMF algorithm.
character string giving the name of the seeding strategy
workhorse function that implements the
seeding strategy. It must have signature
(object="NMF", x="matrix", ...) and initialise the
object with suitable values for fitting
the target matrix
signature(object = "NMFSeed"):
Returns the workhorse function of the seeding method
signature(object = "NMFSeed",
value = "function"): Sets the workhorse function of the
seeding method described by
signature(key = "NMFSeed"): Creates
NMFSeed based on a template object
(Constructor-Copy), in particular it uses the
signature(object = "NMFSeed"): Show
